This looks like a problem of computer precision--failure to represent
numbers like "0.01"  exactly internally-. This is not a formatting
issue-- there have been many posts about this. Convert your variables
to integers --multiply by 100- and work with those.

I can carry out certain commands, such as generate a new variable that has similar values, but I cannot perform other simple tasks such as "browse if variable == .001" or "keep if variable == .001". The variable is formatted as a float (%9.0g), which is a general format that should allow this as I understand it. I was worried that importing the data caused the problem, but when I just open stata and enter similar values, I get the same thing. I also tried reformatting the variable to several different fixed formats, but still no luck. What am I missing? Any thoughts greatly appreciated.
